ABSTRACT:
A privacy screen for a display (e.g., a LCD) having a polarizing film and a birefringent film is described. The privacy screen transmits substantial amounts of light emanating from the display in an orthogonal (or near-orthogonal) direction while not transmitting substantial amounts of horizontal, non-orthogonal light emanating from the display. In this manner, a privacy effect results in that the display is viewable by someone only when that someone is essentially directly in front of the display.
